Abstract 13875: The Ratio of Visceral to Subcutaneous Fat Area is a Sensitive Predictor of Negative Coronary Artery Calcium Score
Aims: Visceral fat area (VSA) is known as a risk factor for coronary artery disease. Recently, the importance of visceral fat to subcutaneous fat area ratio (VSR) is also suggested.
Method: To assess the relationship between calcium score (CS) and VSR ratio, we analyzed the data from consecutive 2520 patients (68+/- 9.5 years, male 59%) who underwent coronary computed tomographic angiography (CCTA). CS, VFA, subcutaneous fat area (SFA), and waist circumference were assessed from axial slices of the abdominal region which were obtained concurrently with CCTA.
Result: Mean VFA, SFA, and waist circumference were 107±59 cm2, 141±73cm2, and 84±10 cm respectively. The median VSR was 0.73 [0.49-1.11]. The median CS was 82.6 [6.70-343] and 464 (20.4%) patients showed negative CS. Comparing ROC curves showed that VSR had a significant better predictive value of negative CS than VFA or waist circumference (p<0.0001).
Conclusion: VSR showed a strong relationship with negative CS. VSR might be a more sensitive parameter than VFA or waist circumference for coronary artery disease.
